9. Beth has 28 math problems for homework. She has 4 times as many problems as her sister, Mary. Which equation shows how many p

Lemur [1.5K]

Answer:

Answer is 28/4 = 7

Step-by-step explanation:

Given

Beth B = 28 problem

B has 4 times more problem than Mery m

Find

Total number of problem Mery m has if Beth has 4 times more problem than Beth

So,

B = 4 x m

m = B/4 = 28/4 = 7

Finally answer (d) is correct which is 28 ÷ 4 = m

A grocery stores studies how long it takes customers to get through the speed check lane. They assume that if it takes more than

Reptile [31]

The probability that a randomly selected customer takes more than 10 minutes will be 8.38%

<em><u>Explanation</u></em>

The average or mean $(\mu)$ is 8.56 minutes and standard deviation $(\sigma)$ is 1.04 minutes.

<u>Formula for finding the z-score</u> is: $z= \frac{X-\mu}{\sigma}$

So, the z-score for $X=$ 10 minutes will be.....

$z(X=10)=\frac{10-8.56}{1.04}=\frac{1.44}{1.04}=1.3846... \approx 1.38$

Now, according to the standard normal distribution table, $P(z$ . So.....

$P(X>10)=P(z>1.38)= 1-P(z$

So, the probability that a randomly selected customer takes more than 10 minutes will be 8.38%

A ball pit at a play area is filled with red and yellow balls. Of the total number of balls 60 percent are red. If there are 720

ser-zykov [4K]

To solve this we'll put the question in this format: x% of y things = z things

We have the percent so we'll put in 60 for x.
Now the total number of balls will be considered y since we have the number of red balls but not blue ones. so we end up having..

60% of y balls = 720 balls

Of is another word for multiplication, therefore:

60/100*y=720
Solve for y
y=1200

So we have 1200 balls

To help answer this question, Deigo wrote the division equation 3/4 divided by 2/5. Explain why this equation does not represent

Mars2501 [29]

Answer:

The fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .

Step-by-step explanation:

Given:

After $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

To find the fraction of the rain that will be filled in the gauge if it continues to rain at the same rate for 15 more minutes.

Solution:

15 minutes in hours will be = $15\ min \times \frac{1\ hour}{60\ min}$ = $\frac{1}{4}$ of an hour.

Given that it has rained for $\frac{3}{4}$ of an hour, and it continues to rain for $\frac{1}{4}$ of an hour more.

Thus, total time of rain will be = $\frac{3}{4}+\frac{1}{4}=\frac{4}{4}=1\ hour$

Using unitary method to find the fraction of rain filled in the gauge after 1 hour of rain.

If in $\frac{3}{4}$ of an hour of rain the rain gauge is $\frac{2}{5}$ filed.

Thus, in 1 hour of rain the gauge will be filled by = $\frac{2}{5}\div \frac{3}{4}$

To divide fractions, we take reciprocal of the divisor and replace division by multiplication.

⇒ $\frac{2}{5}\times\frac{4}{3}$

⇒ $\frac{8}{15}$

Thus, the fraction of the rain filled in the gauge will be = $\frac{8}{15}$

Diego wrote the division equation incorrectly.

It must be given as $\frac{2}{5}$ divided by $\frac{3}{4}$ .
